Setting Up A New SafeCard

New SafeCard? Simply unlock your Lattice1 and insert the card - here's what to do next!
Wallet Setup
Once it's in, you will be prompted to enter a six digit PIN; choose carefully and remember this PIN as you will be unable to change it later and cannot access it. If you do not wish to proceed, remove the card.
You will then be presented with three options for setting up a wallet on your new card: 
Generate Wallet
Restore from Seed Phrase
Restore from SafeCard (impossible to do with a new SafeCard)
If you select Generate Wallet, you will have the opportunity to record your secret seed phrase which you can use for backing up your account. You will also be able to enter an optional 25th word passphrase. 
Please remember that the 25th word seedphrase is a user-generated source of randomness and NOT an unlock password; using a passphrase will change the derived account addresses.
If you select Restore from Seed Phrase, you will have the option to enter a standard 12, 18, or 24 word seed phrase as well as an optional passphrase. If the account you are importing originally included a passphrase, you must use it or you will not see the expected addresses.
If you select Restore from SafeCard, this action will be blocked as you can only restore from a backup SafeCard after a wallet has been generated. When you have a SafeCard with its own wallet, then this action is available when you go to Manage Wallets → Restore from SafeCard.
Seed Exportability
Once your wallet is set up, you will next be asked "Do you want this wallet seed to be exportable?"
Most users should select Yes so that they can use their SafeCard to restore an account to the Lattice1 or copy it to make additional PIN-protected SafeCard backups.
Advanced users may select No if they want unpowered key storage that cannot export the master seed by any means including restoring to the Lattice1, copying to additional SafeCards, or via the GridPlus SafeCard CLI app.
How is SafeCard non-exportability enforced on a technical level?
It's a flag on the javacard applet that is set during the setup process and as javacard applets have persistent memory that does not reset when the chip is removed from contact, non-exportability cannot be updated without erasing a seed from the card.
The only permanent setting of a SafeCard is its PIN code.
There, all done!
